White Rock vs Delaware Chick?

[Solsken Farm]

I cannot tell the difference. They hatched on Monday and arrived this morning. Does anyone have any clues what I might look for to distinguish them?

Thanks

Some delawares have a little bit of black on their heads, but you wil definitely be able to tell when they start to get feathers in as the delawares will have black in their wing feathers. Here are my three dellies as 2-3 day old chicks:

Okay great I will go inspect their wings. I wasn't sure there was any black on them. THANK YOU! Mine would be 3 days old. Bless them.
